On August 1, 2019, GZWDer added PageTriage to [[meta:Limits to configuration changes]] in this diff in the section "Unavailable extensions". That section has since been renamed to "Installation of extensions/skins that are not well maintained". However the effect of it is to advise folks that process Wikimedia-site-requests to never install PageTriage for any wikis.

Once the community is satisfied that PageTriage has enough active maintainers, whether they be volunteers such as myself and MPGuy2824, or the WMF, PageTriage should be removed from this list. We do not want this to block our attempts to make PageTriage wiki-agnostic (T50552), where we will need to install PageTriage on new wikis in order to push development of this forward.
